Troubleshooting
6-32 Manual # 42-02-7223 C1
Earthquake Operation (Counterweight)
Description: The Counterweight Derailment Detector has been activated, indicating an earthquake condition.
Car Reaction: The car will typically make an emergency stop, then move slowly to the next available floor in
a direction away from the counterweight. The fault is latched until the EQ reset button (ICE-EQ board) is
pressed.
Tro ubleshooting:
1. If it is suspected that this event happened in error, check the counterweight derailment detector opera-
tion and associated wiring to the ICE-EQ board.
Earthquake Operation (Seismic Switch)
Description: The Seismic Switch has been activated (input has gone low), indicating an earthquake condi-
tion.
Car Reaction: The car will react as determined by user configuration. (iView/Car Operation/Earthquake) The
car will either make an emergency stop and then move slowly to the next available floor or it will stop nor-
mally at the next available floor in the direction of travel. The fault is latched until the EQ reset button (ICE-
EQ board) is pressed.
Tro ubleshooting:
1. If it is suspected that this event happened in error check the seismic switch input and the associated wir-
ing to the ICE-EQ board. The seismic input is normally on.
Earthquake Reduce Speed
Description: An earthquake event (seismic switch) has initiated a car speed reduction (150 fpm or less) as
required by some code jurisdictions.
Car Reaction: Control stop.
Earthquake Reset Button OK
Description: A previously declared failure of the earthquake reset button has been resolved.
Car Reaction: Previous failure is no longer a reason to keep the car out of service.
Earthquake Reset Button Stuck ON
Description: The controller has detected that the earthquake reset button (located on the ICE-EQ board) has
failed in the “on” state.
Car Reaction: If moving, the car will complete its run. Once stopped, the car is removed from service.
Tro ubleshooting:
1. It is likely that the reset button (or related circuitry) on the ICE-EQ board is faulty.
2. Replace the ICE-EQ board.
Earthquake Run, EARTHQUAKE RUN
Description: Some code jurisdictions allow the car to run normally (at a speed no greater than 150 fpm)
under earthquake conditions. This event indicates that the car is being allowed to run in this manner.
Car Reaction: Car operates “normally” at reduced speed.
Tro ubleshooting:
1. Check the wiring for the seismic and counterweight displacement inputs.
2. Check the earthquake user settings on the Car Operation screen Earthquake tab.
Earthquake Shutdown, EARTHQUAKE SHUTDOWN. See Earthquake Operation Activated.
Earthquake Slow Speed Hoistway Scan Activated
Description: The earthquake hoistway scan (required by section 8.4.10.1.3 of the A17.1-2016 Elevator
Safety code) has been initiated by emergency personnel.
Car Reaction: Car travels from terminal to terminal floor (at a speed not to exceed 150ft/min) before return-
ing to the starting floor without opening doors.
Tro ubleshooting:
1. Check all related earthquake inputs and options.
2. Related inputs: Earthquake Hoistway Scan Switch.
Earthquake Slow Speed Hoistway Scan Deactivated
